Leave it to Hasbro to come up with a great toy called a Ghost Gun. An interesting blend of an MP40 and a flashlight, the Ghost Gun projected an image of one of several ghosts that children of all ages then could use for target practice. My limited research has led me to the conclusion that the Ghost Gun didn’t actually shoot any projectiles, but who cares; it’s a Ghost Gun!
You’ll have to scour eBay for one of these beauties if you want one today, since they’ve been out of production since the 70’s.
